Again, police say only minor injuries. We’ll continue updating here, even as we move on with other news/info. Meantime, a multi-car collision at 1st Avenue South/Spokane was just mentioned on the scanner.

9:19 AM: SPD Blotter has a short summary, most notably mentioning that the container might have been “loose” and destabilized the truck.

9:29 AM: As per comments – and scanner – the light at Delridge/Andover is out. We’re en route to check it out. Remember, a broken stoplight means, treat the intersection like a four-way stop! (Added: Confirmed, it’s out. No crew in sight – but, whether coincidental or not, City Light is working nearby.)

9:58 AM: Hearing it’ll be at least another half-hour before West Marginal is cleared.

10:57 AM: SDOT tweets that final cleanup and towing are under way so it shouldn’t be long. (Added – A moment later, SPD units said via radio that it would be about half an hour.)

Thanks, PP. KING is one of the two TV stations in this area that are generally good about giving credit if it gets info from our coverage (and we are meticulous about giving credit if we use info from other news orgs). – TR

Per police at 8:05 update line above (just before we got there), only minor injuries. Thanks again to the first text tipster (I don’t know her/his identity, only a phone number) for early word on this – at that point it only showed on 911 log as a 4+1+1 SFD incident and not even the fulltime traffic folks we follow on Twitter had word of the truck! We’ll continue updating here until it’s open. – TR

Wonder how it happened. Was it turning onto or off the road? That’s not a super curvy stretch and if it was full of dry concrete something pretty crazy must have been going on to tip it over on its side!

My wife was driving directly in front of the semi when it rolled over. She watched it happen very slowly in her rear view mirror. Scary stuff! She had just passed the truck a few seconds before it rolled.
